The bracelet of ethereum is a unique drop from revenants in the Revenant Caves. Players can charge the bracelet with revenant ethers, and can hold up to 16,000 ether. When charged, the bracelet becomes untradeable and makes the player immune to damage from revenants, with 1 charge being consumed per attack. Revenants are also made tolerant when a charged bracelet is worn.

It is always lost on death, and any ether stored within it will be dropped as well. Thus, it is recommended not to place too many charges in the bracelet, as player killers will always receive the remaining ether within it as loot upon death.

Players can dismantle an uncharged bracelet to receive 250 revenant ethers. This will result in a loss of -311 coins.

As of an update on 11 January2018, players can right-click the Toggle-absorption option on the bracelet to automatically charge the bracelet with revenant ether obtained from revenant drops.
